Abstract

A tank device for a motor vehicle, and a motor vehicle having such a tank device. The tank device includes a motor vehicle tank, a ventilation outlet, and a filler pipe head configured to fill the motor vehicle tank. The filler pipe head includes a filler opening configured to receive a nozzle during a filling sequence, and a filling ventilation opening configured for movement between an open state during introduction of the nozzle to fluidically connect an inner space of the filler pipe head to the ventilation outlet, and a closed state during removal of the nozzle from the filler opening, the filler pipe head having an operational ventilation opening fluidically connected to the ventilation outlet, and which has a semi-permeable diaphragm to permit flow of gasses therethrough and also to prevent a flow of fluids.

Claims

1. A tank device for a motor vehicle, comprising:

a motor vehicle tank;

a ventilation outlet; and

a filler pipe head configured to fill the motor vehicle tank, the filler pipe head including;

a filler opening configured to receive a nozzle during a filling sequence, and

a filling ventilation opening configured for movement between an open state during introduction of the nozzle to fluidically connect an inner space of the filler pipe head to the ventilation outlet, and a closed state during removal of the nozzle from the filler opening, the filler pipe head having an operational ventilation opening fluidically connected to the ventilation outlet, and which has a semi-permeable diaphragm to permit flow of gasses therethrough and also to prevent a flow of fluids.

2. The tank device of claim 1, wherein the ventilation outlet is arranged to lie, when in an installation position, spatially behind the filler opening in a direction of travel of the motor vehicle.

3. The tank device of claim 1, wherein the ventilation outlet is arranged to lie, when in an installation position, spatially behind a wheel arch liner of the motor vehicle.

4. The tank device of claim 1, wherein the filler opening is configured to receive a filling container.

5. The tank device of claim 4, wherein the semi-permeable diaphragm is configured so that ventilation is conducted during the filling sequence, via the filling container through the operational ventilation opening and the ventilation outlet.

6. The tank device of claim 1, further comprising an actuating member configured for displacement to thereby move the filling ventilation opening to an open state during introduction of the nozzle through the filler opening.

7. The tank device of claim 6, further comprising a spring member to pretension the actuating member in a closing direction.

8. The tank device of claim 6, wherein the filler pipe head further comprises a flow-guiding apparatus through which the actuating member is to project.

9. The tank device of claim 6, wherein the semi-permeable diaphragm is arranged radially outside the actuating member.

10. The tank device of claim 1, further comprising a flap configured to pivot when in contact by the nozzle to thereby move the filling ventilation opening to an open state during introduction of the nozzle through the filler opening.

11. The tank device of claim 1, further comprising:

an actuating member configured for displacement to thereby move the filling ventilation opening to an open state during introduction of the nozzle through the filler opening; and

a flap configured for pivoting movement when in contact by the nozzle to thereby move the filling ventilation opening to an open state during introduction of the nozzle through the filler opening.

12. The tank device of claim 11, further comprising a spring member to pretension the actuating member in a closing direction.

13. The tank device of claim 11, wherein the filler pipe head further comprises a flow-guiding apparatus through which the actuating member is to project.

14. The tank device of claim 11, wherein the semi-permeable diaphragm is arranged radially outside the actuating member.

15. The tank device of claim 11, wherein the flap is configured to pivot in an opening direction by displacement of the actuating member during introduction of the nozzle.

16. The tank device of claim 1, further comprising:

a ventilation path arranged between the operational ventilation opening and the fuel tank; and

a restrictor may be arranged in the ventilation path to prevent rising fluid in the ventilation path during the filling sequence, from reaching the filling ventilation opening.

17. The tank device of claim 1, further comprising:

a ventilation path arranged between the filling ventilation opening and the fuel tank; and

a restrictor may be arranged in the ventilation path to prevent rising fluid in the ventilation path during the filling sequence, from reaching the filling ventilation opening.

18. The tank device of claim 1, wherein the motor vehicle tank comprises a urea tank.

19. A motor vehicle, comprising:

a tank device that includes a motor vehicle tank, a ventilation outlet, and a filler pipe head configured to fill the motor vehicle tank, the filler pipe head having;

a filler opening configured to receive a nozzle during a filling sequence, and

a filling ventilation opening configured for movement between an open state during introduction of the nozzle to fluidically connect an inner space of the filler pipe head to the ventilation outlet, and a closed state during removal of the nozzle from the filler opening, the filler pipe head having an operational ventilation opening fluidically connected to the ventilation outlet, and which has a semi-permeable diaphragm to permit flow of gasses therethrough and also to prevent a flow of fluids,

wherein the ventilation outlet is arranged to lie, when in an installation position, spatially behind a wheel arch liner of the motor vehicle.
